I found that I was trying too hard. I was "staring" to get that blip. Once I relaxed and stopped caring about the blip, it got much easier to get and to maintain. My eyestrain also went down dramatically.
Finally, I found myself looking at each page for quite a long time. It would take 20-30 minutes to PhotoRead a book. As I relaxed and realized that I didn't have to "burn" the image into my brain, things got much easier. I can now PhotoRead a book at a page per second, keep my focus, and keep my concentration.
Relax, cut yourself some slack, and do 2-3 books/day. That helps tremendously.
